WATCH LIVE: Senate expected to vote on DHS secretary confirmation for Mullin

The Senate is preparing to vote on confirming Markwayne Mullin as homeland security secretary, Trump's replacement pick after the president fired Kristi Noem from the role. Noem's departure followed public criticism over the administration's aggressive immigration enforcement and mass deportation policies. Mullin, a Republican from Oklahoma, is expected to be confirmed to lead the Department of Homeland Security during a period of significant upheaval in the agency's leadership and operations. The confirmation vote signals the administration's intent to move forward with its border and immigration agenda despite the controversy that led to Noem's removal. The DHS oversees border security, immigration enforcement, and disaster response, making the secretary's position central to Trump's domestic priorities.
